Power up your vocabulary—or just learn a bunch of really neat words, and where they came from—with this daily desk calendar from Merriam-Webster. Here are mythological words (Fata Morgana), scientific words (stridulate), words borrowed from other languages (vamoose), and words to make you sound smarter at cocktail parties (bildungsroman). Saturdays and Sundays share a page, but you get two words.
